Justin Bieber tried to monkey around in Germany, literally -- but officials are having none of it. Landing in Munich on Thursday March 28 for a concert, the 19-year-old pop superstar was forced to leave a capuchin money in quarantine after he failed to produce the the necessary papers for the animal, authorities explained on Saturday.

The "Beauty and the Beat" singer attempted to go through customs with the animal, but had to leave it at the airport following a discussion with officials customs spokesman Thomas Meister said, according to the Associated Press.

"Munich was a good time. And loud. The bus is headed to Vienna now. U coming?" Bieber tweeted after the show, although he didn't mention the monkey. Before leaving the U.S. on Wednesday, he had a brief, one-hour reunion with ex-girlfriend Selena Gomez at her L.A. home. Earlier in the week, Bieber spoke with Us Weekly exclusively about the recent spate of negative press attention he's received.
